COX-2-independent effects of celecoxib sensitize lymphoma B cells to TRAIL-mediated apoptosis.

Purpose: Despite therapeutic advances, non-Hodgkin lymphomas (NHL) remain incurable. They form a group of neoplasms strongly dependent on their inflammatory microenvironment, which plays an important supportive role in tumor B-cell survival and in the resistance to antitumor immune response. New therapies must consider both tumor cells and their surrounding microenvironment

Experimental Design: Stromal cells, derived from bone marrow or lymph nodes, and B cells from follicular lymphoma patients were cocultured or cultured alone with celecoxib treatment, a nonsteroidal anti-inflammatory drug, and/or TRAIL, a promising cytotoxic molecule for cancer therapy.

A new prognostic clinicopathological classification of pituitary adenomas: a multicentric case-control study of 410 patients with 8 years post-operative follow-up.

Pituitary adenomas are currently classified by histological, immunocytochemical and numerous ultrastructural characteristics lacking unequivocal prognostic correlations. We investigated the prognostic value of a new clinicopathological classification with grades based on invasion and proliferation. This retrospective multicentric case-control study comprised 410 patients who had surgery for a pituitary tumour with long-term follow-up.

Clarithromycin stops lung function decline in airway-centered interstitial fibrosis.

Airway-centered interstitial fibrosis (ACIF) is a distinct type of lung interstitial fibrosis characterized by lesions centered on the airways. Several cases reported in the literature showed little to no effect of corticosteroids and a high mortality rate in the absence of lung transplantation. No other efficient approach is described for the treatment of this type of fibrosis.

[Acute respiratory distress syndrome related to intra-alveolar hemorrhage revealing a vasculitis].

Intra-alveolar hemorrhage (IAH) could be revealed by acute respiratory failure. The classic association of hemoptysis - anemia - radiological infiltrates is suggestive and has to be confirmed by broncho-alveolar lavage with Golde score. Etiologies included immune and non-immune diseases, with specific treatment for each.

Combination of rituximab, bortezomib, doxorubicin, dexamethasone and chlorambucil (RiPAD+C) as first-line therapy for elderly mantle cell lymphoma patients: results of a phase II trial from the GOELAMS.

Background: There is no consensual first-line chemotherapy for elderly patients with mantle cell lymphoma (MCL). The GOELAMS (Groupe Ouest-Est des Leucémies Aiguës et Maladies du Sang) group previously developed the (R)VAD+C regimen (rituximab, vincristine, doxorubicin, dexamethasone and chlorambucil), which appeared as efficient as R-CHOP (rituximab, cyclophosphamide, doxorubicine, vincristine, prednisone) while less toxic. Based on this protocol, we now added bortezomib (RiPAD+C: rituximab, bortezomib, doxorubicin, dexamethasone and chlorambucil) given its efficacy in relapsed/refractory MCL patients.
